AB350 K4 Gaming - turns on and off

turning off xmp wont hurt it will just slow down the ram to defualt (usually 2133)

from memory i think the earliest bios versions had a 5 or 6 reboot setting (dont quote me its late)
whereas as parsec says the later ones are set to 3 trys

Welcome to the Ryzen platform!

What you are most likely experiencing is a feature that is enabled by default in the UEFI/BIOS. That is the AM4 Advance Boot Training option/feature, found in the OC Tweaker screen.

The purpose of that option is to perform what is called "memory training" on the AM4 platform. It will attempt to tune the memory settings, normally for any memory OC that is applied. Sometimes it will do just what appears to be a "boot loop", where the board restarts itself multiple times without really shutting off. At other times, more rare, it will actually turn the PC on and off a few times instead. That is usually due to a failed memory over clock that cannot be tuned by this feature. Most if not all Ryzen board users have experienced this behavior.

Try setting the AM4 Advance Boot Training option to Disabled, and see if you still have the on and off sequence still happen, usually from a cold start.

There is an option associated with the AM4 Advance Boot Training option, called Retry Count, which might not be on the same screen as the AM4 Advance Boot Training option. That is the number of times the restart or on/off sequence will occur, which is set to three by default. Does three times on and off seem familiar?

This behavior is normally associated with a memory over clock, or memory that is compatible only at lower speeds. Do you have your memory over clocked? What speed do you use for your memory?

Occasionally, the restart or on/off sequence will occur even with stock memory speeds, for reasons that are not known.

Hi all,
